Filling Index

The cluster mechanism uses a internal variable called the filling index. During a transfer, this variable designates the surface of the cluster which is currently receiving an image. Otherwise, it designates the surface which has been elected to receive the next image.

In other words, when the acquisition sequence is alive, the filling index designates the FILLING surface in the cluster.

The designation uses the zero-based surface index associated to each surface of the cluster.
